MAX6368HKA23+

Overview

The MAX6368HKA23+ is a low-power supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand, housed in an SOT-23-8 surface-mount package. It features a fixed reset threshold voltage of 2.30V and supports a maximum supply voltage of 5.5V. The device provides an active-high, open-drain output with a standard reset delay time of 280ms. It operates within a temperature range of -40°C to +85°C and consumes a typical quiescent current of 15µA. Key functional attributes include battery backup switching capability and chip-enable gating, while it lacks manual reset inputs and watchdog timer functionality.

Feature Summary

• Integrates battery backup switching for seamless power transition management
• Includes chip-enable gating for precise power control and system state management
• Delivers active-high open-drain reset signal output

Applications

• Portable electronic devices requiring low-power voltage supervision
• Battery-operated systems needing backup power switching
• Embedded microcontroller reset circuits

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential availability constraints. Confirm RoHS compliance status and specific lot traceability requirements before procurement. Ensure storage conditions align with manufacturer guidelines to maintain device integrity. Cross-reference ordering suffixes to confirm exact electrical characteristics and packaging specifications match project requirements.

Selection Notes

Select this component when a fixed 2.30V threshold is required for single-input voltage monitoring. Consider the SOT-23-8 footprint for space-constrained designs. Evaluate the 15µA quiescent current against system power budgets. Verify compatibility with active-high logic interfaces. Note that adjustable thresholds are not available in this specific variant.

Part Context

This part belongs to the MAX6368H series of uPower Supervisors from Maxim Integrated. The series offers various threshold voltages and output configurations within the same SOT-23-8 package family. It is designed for applications demanding minimal standby current and reliable reset generation in portable and battery-powered environments.

Replacement Considerations

Check MAX6368HKA29+T for a 2.90V threshold alternative. Review MAX6368HKA31+T for a 3.10V threshold option. Compare MAX6368LKA44+T if push-pull output is preferred over open-drain.
